EW also debuted the first promo for the spinoff series, and it’s filled with a ton of action and all the Winchester snark and humor you could wish for in a series that won’t even star the brothers we’ve come to know and love for nine seasons. That’s right: “Supernatural: Bloodlines” will feature an all-new cast of characters, and Sam and Dean will remain firmly on the original, parent series for Season 10 (let out that big sigh of relief in 3 … 2 … 1 … ).

Plus, “Supernatural: Bloodlines” is set in the beautiful city of Chicago, so we’ll get to see the Winchesters take on a case in a big city for once. No small towns or crappy motels for these guys — at least for one episode.

Check out the promo for the potential spinoff pilot/episode 20 of “Supernatural” below:
